| 摘要: |
| 利用新型储能器件超级电容器可短时快速大功率充放电的特性，并结合四象限电压源型变流器有功功率和无功功率解耦控制策略，抑制风电场输出有功功率和无功功率波动，稳定风电场输出母线电压。将双向直流变换器作为超级电容器的电压适配器，解决其端电压波动并维持放电时直流母线电压稳定。在电力系统仿真软件DigSILENT／PowerFactory中对采用超级电容器储能系统抑制风电场输出功率波动和提高电压稳定问题进行了仿真分析，结果表明超级电容器储能系统达到了有效的运行特性。 |

| Abstract: |
| As the new energy storage device EDLC（Electric Double Layer Capacitor） can be quickly and completely charged and discharged with large power，it is used，combined with the active and reactive power decoupling control strategy of four-quadrant voltage source rectifier，to suppress the output power fluctuation of wind farm and stabilize its output bus voltage. Bi-directional DC-DC converter is used as the voltage adapter of EDLC to suppress its terminal voltage fluctuation and maintain the voltage stability of DC bus. The effective operation of the proposed EDLC energy storage system is verified by the simulation with DigSILENT／ PowerFactory. |
